To all whom it may concem:

Be it known that L'Cnnnnss NorthPlainfield, Somerset county, State of New J er'sey, have invented Improvements in Combined- Telephone and Fire-Alarm Systems; of whic'h the following is a specificm tion; the same bein a division otmy appli cation entitled ombined firea-larm and extinguishing systems, filed May 10, 1900 and-serially numbered 16,239.

The invention relates tothe combinatiom over the telephone circuit to thecentralsta- ,ti'on designatim the location of the place where thej sprin ler has opened. The invention further consiststin the com- 'bination, with the" telephone system and the sprinkler system,'- of a main valve for the sprinkler'system, and means wher'eby vhen said valve is moved from its position of fully open the same definite number signal will.

likewise be sent over the telephone circuit to the central station.

The invention furtherconsists' in the combination, with the telephone system and the sprinkler system, of a main valve for said sprinkler system, of means whereby when said valve 1s moved from its position of fully opena definite numbersignal willvbe sent over the telephone circuit to the central stafl tion and a supplemental or seeon'dar'y alarm will also be sent to, sa'idr'entral statiour Thefmveutlou f'urther-(rmrstfi s m the 'comafter 'd eser'i'bed' and "elai med.

D is a generator the ari'uature of which is carried by the shaft in of the motor M, and so that when said motor is operated by the flow of water thereto said armature will be rotated and a The circuit 1, 1, leads to the telephone T located at the building where the sprinkler stem shown is installed. The telephone circuit which connects the tele hone '1 with the switch-board at the centra station normally leads through. the pressure gage G by reason of the contact of the pointer with the contact 0, which contact is maintained so long as there is no pressure in pipe The generator D is included in a branc circuit .2 2 leading from the main telephone circuit,

Normally the generatorD 1s shunted out of the telephone circuit by means of the short path which leads through the pressurega eG. c

Mounted in a suitable position to be engaged by said projections c a springs, as shown in connected to one of the wires while connected to the other wire a is a contact j c, the

A line leads from one of the wires .2 to the spring 8 which is arranged to be engaged by an insulated projection K' on the handle H ofthe valve owhen said valve is in its fully open position, as shown in Fig. 1. The contact i is arranged in proximity to the spring 8, said contact being connected by a wire with the water-pipe and thereby grounded. A groundedwire Z) is connected with the switch-board at the telephone station, which said grounded line includes a bell b. With this arrangement, whenever the handleH is moved to turn the valve from its fully open. position, the projection K will be moved from beneath the spring .9, which will thereby be permitted to come in contact with the contact :1 and thereby close the grounded line formed by one side of the main telephone circuit and thereby ring the hell Z1.

The operation of the apparatus above described 18 as follows: Whenever a sprinkler opens, or whenever the, valve 0' is moved from its fully open position, the valve R V will be opened by the water-pressure on the supply side to permit the flow of water through the 'pipe to operate the watermotor M and thereby start the generator D and also rotate the number wheel 10 The water-pressure inthe pipep will serve to move the pointer on the pressure-gage G out of cont-act with the contact which will serve to throw the generator into the telephone erator will flow over the telephone circuit to the central station and will there operate the drop of the enunciator connected with that circuit, and the operator at the central station will hear through the receiver the number signals sent over the line by the generator under the action of the number wheel. -As such number signals will be thus sent over the telephone circuit and heard on the receiver at the central station, both when the sprinkler opens and when the main valve is moved from its position of fully open, it is the operator should know whether the alarm so sent is a sprinkler alarm or a valve-alarm, and for this purpose the secondary grounded circuit above described is employed, and so that when the alarm sent over the telephone circuit is a valve-alarm this fact will be denoted by the ringing ofthe bell 6 closing of the grounded battery circuit 6" the contact of the spring a with the contact z. When the arrangeuu-nt shown in Fig. 3 is employed in place words which may be impressed upon the phonogra 'rh cylinder will, by the variation in pressure between -,t-lm constant contact electrodes, be causcl to be transmitted over.

which is effected by the '120 of the number wheel any phone circuit to the central station and.

.where they will be heard upon the receiver at said station.- It will be understood that, when the phonograph is used, central is called by the generator D in the same manner as when the'number-wheel is used.
